The hippocampus, posterior cortex and cerebellum of Tg2576 mice have measurable Aβ1–42 and display increased CaN activity, which is reversed by treatment with FK506. a) CaN (PP-2B) enzymatic activity assay and b) human Aβ1–42 ELISA in the hippocampus (HIPP), posterior cortex (PCTX) and cerebellum (CB) of 5 month old Tg2576 mice treated with FK506 (10 mg/kg ip) 6 hr before sacrifice. Bars represent the average ± S.D. of five animals per group. *p<0.001 vs. vehicle-treated wild type (WT) mice (two-tailed Student’s t test with Bonferroni correction for multiple comparison). n.d.: none detected (below the ELISA detection limit).
